Abstract

La présente invention concerne un ensemble joint composite mécanique fendu pour réaliser un joint entre un arbre tournant et une surface statique. L'ensemble joint composite mécanique fendu comprend des premier et second éléments d'étanchéité annulaires adjacents dans le plan axial. Les premier et second éléments d'étanchéité comprennent chacun une arête d'étanchéité entrant en contact avec l'arbre pour fournir un joint respectif entre le premier et le second élément d'étanchéité et l'arbre. Un boîtier statique reçoit les premier et second éléments d'étanchéité et interagit avec la surface statique pour fournir un joint stationnaire statique tout en fournissant une région de flexion interagissant avec les éléments d'étanchéité pour former un joint dynamique avec eux. Un ensemble de support reçoit un élément d'étanchéité et peut comprendre une entrée à angle double pour faciliter le montage de l'élément d'étanchéité. L'ensemble de support peut comprendre une rainure de verrouillage pour recevoir et retenir un joint torique disposé autour de l'élément d'étanchéité. Le boîtier statique peut comprendre deux segments conjugués ayant des surfaces se chevauchant.
